Webwhen you take the 3 numbers in AP as a-d, a and a+d, you can cancel out the 2 ds ( d and -d) and get the value of a quickly. You can also take the number as a, a+d and a+2d but this will make your calculation complicated and you will find it diificult to get the final value of a and d. Lawrence C.
